. 5 film can. be wound and severed so that the film the film may passwhen the shutter is moved to an inoperative position byplacing themagazine in the camera. Another object of my invention is to provide ameans for severing the film and for automatically threading it into themagazine reel when the magazine is removed and inserted into a camera;,Still anotherobiect of my inven- 'tion is-to proyide a'magazine whichrequires the minimum amount of manipulation and which can be readilyhandled by an unskilled operator.

The magazine construction which will be more fully hereinafter describedis particularly de- -v signed for use in the apparatus shown in my twogranted August 18, 1938, and 2,051,!93 for Camera back construction,granted August 18, 1936. These two applications show features of acamera designed primarily ,for taking portraits to be used in a studioin which aseries of photographs are rapidly made on a strip of rollfilm. These photographs may be made either singly or in stripscontaining a number'of exposures, it being oneof theobiects ofmyinvention to provide an apparatus which may make five or six pictures ina very few seconds so that the photographer can select the exposureshaving the best, expressions for producing portraits. 4 Such a cameramay use anysizeof filmbut it 7 is intended to usefiim 70 Math, thisbeing found a satisfactory size for my purpose. The

film may be supplied in relatively long rolls, such andit isintendedthatthismagazine should be;

(Cl. s s-si) s of perhaps six exposures each, it would probably beconvenient for him to cut off the film and remove the magazine so thatan assistant can pro-v ceed with the development of the film. However,

the amountof film which can be wound on the take-up magazine and itsmethod of use is largely optional.

ent of my In a camera constructed in accordance with I the showing of myco-pending applications above referred to, the camera body I is providedwith a bottom wall 2 through which a slot I extends'topermitafilml'topassfromtheexposure frame into a take-up magazinedesignated broadiyasl. Ontheside walls f the camera, near the bottomwall I, there are grooves t to receive the side edges of a slide I whichperforms two functions, that is it slides the magazine I from the cameraat the sametime it sever's the film F.- This is accomplished in thefollowing manncrz:

'Iheslidel hasaslottnormally registering with the slot 3 in the camerawall, but when the handlelis drawn inthe direction of the arrow showninl'ig. Ltheslidemovessothattheedgeofthesiotlcutsthefilmastheslidemovestothepositicnshowninl'ig. 4. Asthehandlelis drawn outahookilengsgesaresrwall Ii ofthemsgazine 4 so that themagazine moves from the camera with the slide 1 which comprises theknife. However, as soon as the movement of the knife is stopped, bymeans 0! the pin I2 reaching the end of a slot i3 in the slide I,further move-' ment of the magazine can only take place when the springlatch I4 is swung about the hinge pintle l5 so that the aperture I3 isdisengaged from. the pin II. The magazine may then be pressed.downwardly to clear the hinged latch member, this action being possiblebecause of the spring i8 carried by the camera wall It. This spring isthe sole means for holding the magazine tightly in contact with thecamera wall 2.

In order to afford a light-tight connection between the magazine 4 andthe slide i, a layer of velvet, plush, or other suitable material it isprovided, as clearly illustrated in Fig. 1. This material tightlyengages both the slide I and the slide .28 to provide an eflective lightlock therebetween when the magazine is secured to the camera.

It is, of course, necessary to render the magazine light-tight before itis removed from the camera body. This is accomplished by means of aslide 20 which, as best shown in Fig. 3, is mounted on the top wall 2!of the magazine 4 and is so arranged that it may slide in a recess 22which may be formed in the top wall of the magazine. The movement oi theslide is caused by a spring 23 which exerts a thrust in the directionshown by the arrow in Fig. 3. However, when the magazine is in theposition shown in- Fig. 1, the slide contacts with the pin l2 extendingdownwardly from the camera wall 2 so that a slot 24 in the slideregisters with the slot 3 in the magazine wall and with the slot 3 inthe slide 1.

this reel is driven by power. A shaft 28 carries a disk 29 which isadapted to engage between a pair of spring disks 30 which are powerdriven by a shaft-3l from a suitable source of power not w shown in thisapplication. The spring 'disks 3!! only frictionallyengage the smoothperiphery o the disk 29, and consequently there is a slip drive whichcan readily take care oi the small diflerence in driving speed due tothe varying diameter of the take-up reel.

The take-up reel-consists of a pair of similar spaced flanges 32'mountedto turn freely on the shaft 28, there being a series of curved,arcuateshaped spoke members 33. These spoke mem-' bers, as best shown inFig. 2, are made slightly concave in form so that a film F wound uponthe spoke members will contact only at the extreme edges near theflanges 32 and will eliminate the possibility oi scratching either"surface of a film wound thereon. In order to turn the a the spokemembers 33 bypassing through the g cut-out notchesfl of the spokes.Thus, when ends by walls 83 to form a housing in which a It flanges,

there is no film on the valve idly.

' When the film'F is moved downwardly through the registering openingsinto the magazine 4, the guiding plate 39 directs the film between apair of spoke members 33 against'one oi which the film is clamped by thearms 40. The space between the arms 40 and the spokes 33 is less thanreel 21, the arms may rethe thickness of the film, 'so that the points4| of the arfns will anchor the end of the film in place. The reel isnot moving as the end of the film approaches, but since the film isbeing moved, and the shaft 23 with the arms 40 are driven .by a sourceof power, not shown, as soon as the film is clamped against the spokemembers .33, the reel will be turned also. Since these arms strike thesurface of'the film F, the film will be unable to bend through thenarrow notches 33 in the ends of the spokes, and the reel will start toturn, being turned through the action of the arms 40. Thus, the end ofthe film is immediately locked against the take-up reel and the .disk29'will continue to drive the reel as long as the camera continues torun. After the desired amount of film is wound on the reel the camera isstopped, the handle 3 is drawn out by the operator, sliding the magazine4 from the camera body, permitting the spring 23 to close the slot 24,rendering the magazine light-tight, and moving the magazine to a pointat which it can readily be grasped by an operator. By releasing thespring latch i8--| 'I, and pressing slightly downwardly upon themagazine it can be withdrawn from above thespring I8.

In order to remove film which has been wound on the reel from themagazine it is only necessary to withdraw the top 44 which iorms thecover oi the magazine and which carries with it the disk 29, shaft 28,and reel 21. Thus the film is readily accessible for removal for thefiuid treatment operations.

' In order to prevent the reel 21 from turning too freely, I prefer toprovide a tensioning spring 45 on the bottom wall 46 of the magazine,this spring being arranged to press on one of the flanges 32. The end ofthe shaft 23 is provided with an aperture 41 aiiapted to engage a pin 43in the bottom wall 46 of the magazine when the cover is on the magazineand the reel has been" inserted into its operative position.

. Referring now particularly tb Figs. 5-9 inclusive, wherein a secondand preferred embodiment of my invention is shown, the. magazine holdingstructure is somewhat diflerent from that described above. 'As indicatedin Fig. 5 the camera ill is provided with a bottom wall 5| having a slot52 through which the film F may pass to the magazine 53. A rear wall B4of the camera extends downwardly, and there is a bottom wall 55 forminga box-like housing with the side walls 56 for receiving-the magazine 53.In order to hold the magazine in its operative position I provide aplurality of balls 51 which are" 53' is withdrawn from the housing theballs will not be released and move into the housing. The apertures illare, of course, larger at the bottom than they are at the top of thewall.

A front wall 61 of the camera is provided with Y an inverted cup-shapedwall 62 connected at the cover member is in the shape of a shallow,boxlike enclosure and is provided with a rear wall 66, side walls 61,and a bottom wall 68. A spring 69 is mounted in this cover to press themagazine 53 into an operative position, and a snap-latch consisting of alug iii adapted to snap into an opening in a spring II is used to holdthe cover in a closed position.

When in this position a flange I2 engages a cooperatingflange I3 on theend of wall 62 to form a light-tight connection. When thesnap-latchIO-Tl is released, the cover may be swung about the hinge pintle 64 fromthe position shown in Fig. 5 to the position shown in Fig. 6., Thismovement not only opens the cover, but because the hinge pintle 64 iskeyed to the cover 66 it turns with it. Mounted on the pintle 64 are apair of gear members I5, these gears having teeth adapted to engage inapertures 16 in a slide 11 carried by camera wall 5|.

Like the slide I, slide 11 performs two functions, in that it servesas"a knife when the edge 18 passes the slot 62, through which .fllmpasses to the magazine, and because of the downwardly extending lugs 19the slide 11 likewise movesthe magazine 53 from the camera.

The magazine 53 is provided with a somewhat difierent type of shutter torender the slot 86 through which film passes to the magazine lighttightas the magazineis withdrawn from the camera. As best shown in Fig. 9 thetop of the magazine carries a shutter member comprising a slide 8|including a slot 82. Slide is pressed by spring 83 lying in a recessbeneath the cover plate 64 in the direction shown by the arrow, thecover plate 84 being notched at 65. The top of the magazine 53 isrecessed at 86 so that when the magazine is moved into the camera, a pin61 on the camera wall 6i can pass through theslot' 86, engage the edge68 of the slide 6!, and move it to a position wherein the slot 62 willregister with the slot 69 in'the cover plate, so that film can passthrough this opening.

The cover plate 84 may be held on as by a series of screws 96 so thatthe top of the magazine will present a smooth surfacewhich will slidereadily into the camera.

Between the cover plate 64 of the magazine and the slidable plate I1which forms the knife for cutting off film, there is a supplementaryshutter member 92, as best shown in'Fig. 7-. The reason for thissupplementary shutter member 92 is that it is necessary to form a coverfor the slot 52 when the magazine is removed just as it is necessary toform a. cover for the slot 69 in the magazine. The plate 92 is mountedto slide on rails 93 formed up near the top of the side walls 56. Theserails are provided withnotches 94 into which the downwardly formedspring arms 95 of the slide 92" may snap as the slide is drawnoutwardly. The outward movement of the slide is due to the frictionalengagement with the top of the magazine 53.

When the door 66 has been swung open as indicated in Fig. 6, thesupplementary slide or shutter 92 is'in the position shown in Fig. 6.When, however, amagazine isinserted, the magazine engages a pair ofdownwardly extending arms or] gs 96 on the end of slide 92 moving theslide inwardly as the cover 66 is closed. This will permit the pin 81 toslide through a slot 91 cut in the slide 92'. Before'the. slide starts 3to. move the top wall of the magazine engages the underside of thespring arms 95 at the cam surfaces 95* thereof and cams them out of theslots 94 in the siderails, permitting the slide member to move. Thecover can then be closed to hold the parts in an operative position. Theslide 92 is provided with a slot Hill which is arranged to register withthe slot 52 when the.

wound through the cooperating slots 52 and 89,-

and it is desired to remove the film in magazine 53, the door 66 isswung open, thus causing the gear 15 to turn, and by meshing in theaper-' tures 16, to slide the knife member 18 across slot 52 thussevering the film. As the magazine 63 moves outwardly the slide 6i ofthe magamne under the impulse of spring 83' moves toward the positionshown in Fig. 9, so that the slot 99 is completely covered before themagazine is withdrawn from the camera. As the magazine is drawn out it aso moves the slide 92 so that it will cover up the slot 52 before thedoor is completely opened, and any film remaining in the camera 5i willbe adequately protected from light.

The interior construction of the magazine 53 is exactly like theinterior construction of the magazine 4 shown in the first four figures,that is, the magazine is provided with 'a cover member 96 on one side,this cover member carrying a driving disk 99 and a reel constructionexactly the same as the reel in the first-mentioned embodiment of myinvention.

When an operator desires to place a fresh magazine in the camera, it isonly necessary to slide the magazine 53 into the camera and close thedoor 66, thus opening the slots 52 and 69 so that film F can be passedinto the magazine. As the film passes through these slots it may strikethe plate 39 so that the end of the film will be directed between a pairof the spokes 33 in position to be caught by one of the arms 4i, .sincethe arms are driven and the reel and spokes remain stationary up to thetime that film is caught between an underside of a spoke and an arm 4|.As the arms 4! continue .to rotate under power derived through thedriving disk 99, the entire reel is turned to wind convolutions of filmupon the spokes.
